  1. 1. Numerical Accident Reconstructions A Biomechanical Tool to Understand and Prevent Head Injuries

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Madelen Fahlstedt; KTH.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head injuries; Accident Reconstruction; Finite element analysis; Injury prevention; Helmet; Cyclist; Pedestrian; Epidemiology; Applied Medical Technology; Tillämpad medicinsk teknik;

    Sammanfattning : Traumatic brain injuries (TBIs) are a major health and socioeconomic problem throughout the world, with an estimated 10 million deaths and instances of hospitalization annually. Numerical methods such as finite element (FE) methods can be used to study head injuries and optimize the protection, which can lead to a decrease in the number of injuries. LÄS MER

  2. 2. Holocene Climate in Central and Southern Sweden Quantitative Reconstructions from Fossil Data

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Karin Antonsson; Uppsala universitet.; [2006]
    Nyckelord :Quaternary geology; pollen analysis; climate reconstructions; transfer functions; vegetation dynamics; Sweden; Kvartärgeologi;

    Sammanfattning : In quantitative palaeoecology modern species-environmental relationships can be statistically modelled, and recent development has made the calibration models more statistically robust. These models are used to transform fossil assemblages to quantitative estimates of past environmental conditions. LÄS MER

    Sammanfattning : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.

  5. 5. Child Safety in Car Crashes

    Detta är en avhandling från Umeå : Arkeologi och samiska studier

    Författare :Marianne Andersson; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reconstructions; near-side; evaluations; frontal impact; rigid body; mathematical simulations; rear seat; finite elements; belt positioning booster; side impact; child safety; child seat;

    Sammanfattning : Traffic related trauma is the most common cause of fatality and severe injury to children in developed countries. The majority of these fatalities and injuries are caused by frontal and side impacts. LÄS MER
